MILEAGE-PERIOD-SIGNALIN DEVICE.

7 Application filed January 28, 1921. Serial No. 440,6Q4.

I To all whomz't'mag camera:

Be it known thatI, CHARLES S. BURTON, a citizen of the United States,and a resident of ()ak Park, in the county of Cook and State ofIllinois, have invented certain new and u'seful Improvements inMileage-Period- Signaling Devices, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof.

The purpose of this invention is to provide an odometer. with asignaling device intended to be operated periodically upon thecompletion by the odometer of a redetermined mileage record of the vehice served by the instrument for calling attention of the driver to somerequirement of the vehicle or its motor. It consists in the elements andfeatures of construction shown on Fig. 3.

and-described as indicated in the claims.

In the drawings Fi ure 1 is a face view or elevation of a spec ometercomprising an odometer train and indicating devices and equipped withdevices which constitute the present invention.

'ig. 7 is a section at the line, 7-7, on

Fig. 6.

- igs. 8, 9 and 10 are views similar to Figs. 6, 7 and 8, (omitting thedog), showin a slight modification.

' igs. 11 and 12 are views similar to Figs. 6 and 7 showing anothermodification.

The drawings show an odometer train and face plate of familiarconstruction, requiring no description as to details beyond indicatingcertain wheels with which the auxiliary train provided for the purposeof the present invention is connected.

A is a gear fixed with respect tothe tens column number wheel of thefront of the odometer number train, said number wheel,

the gear, A, revolving tooth-by-tooth with said gear. These two wheelsare parts of the original odometer train. B is a gear having the samenumber of teethyas thegear,'A, which meshes with the pinion, A havingbearings provided for it at 0 on a bracket, C, which is mounted in anyconvenient manner fixedly with respect to the odometer train. support orcasing. Ri id with the gear, B, is a beveled 'plnion,

which'meshes with a beveled gear, B having more than twice the number ofteeth of the beveled pinion, so that it will make one revolution insomething more than two hun- Specification otLettersPatent. PatentedNov. 1,1921- dred miles travel indicated by the odometer..'

Suitable bearing is provided for the shaft, 11 of the beveled ear, Bwhich shaft extends at right an des to the face plate, E. Said face Backof the plate there is mounted a signal,

F, pivoted by means of the spindle, F for swinging to display throu hthe aperture and to remove from disp ay position, "a

plate has-a signal aperture, E

signal suitable for indicating the attention required and of which it isthe purpose of the particular device to warn the driver of the vehicle.In the present instance the par-- ticular attention contemplated is tosupply lubricant to the motor; and consequently the target carries thesignal Oil; and the target has a width at the point at which it swingspast the open face somewhat more than double that required for saidsignal Oil, so that at one limit of its movement the signal may bedisplayed through the side opening, and at the other limit said sideopening may be closed by a blank area of the target, said signal beingconcealed behind the face plate.

The face plate, E, has an aperture, E,

alined with the shaft, 6 and upon the u wardly protrudingend portion ofsaid sha 6 there is mounted a. hollow sleeve shaft,

J telescoped thereon with a rather tight frictional fit and having aknob, J, accessible above the face plate for rotatin the sleeve toadjust it and the parts WhlCh it carries as hereinafter described,relatively to the .shaft, 6 and to the odometer train d'readings, Rigidwith the sleeve shaft,

I J is'a disk, K, which constitutes one memstituting one track fouthedog, and said disk is rabbeted or cut back in diameter forming a secondtrack at is, laterally situated'wlth respect to the track, A, andradially inward t erefrom. At one point 1n the circumference of thetrack, K, it is interrupted by .a notch, in, of which the back or.bottom is sloped as seen at In, so as to present an inclined guidewayfor the dog to cause the latter when it runs off the outer track, 70,into said notch, to be deflected laterally while it is moving radlally,and thereby caused to reach and lodge upon the inner and laterallysituated track, a The dog referred to is shown at L, pivoted at Z to thehub, F, of the target, F, by whlch said target is pivotally mountedabove the stud, F for swinging as described in a lane parallel to theface plate; and said og, it will be observed, by bemg pivoted asdescribed to said hub, is adapted for swinging in a plane transverseto'the plane of the target. The stud is positioned and the dog extendedtherefrom so that the nose, L of the dog may ride upon either of thetracks, in, 01570 of the disk, K, the dog turning about its pivot atZ,-bringing its. nose into the 1pIlane of one track or the other.- .Aspring, coiled about the stud, F has one end engaged with the stud andthe other end engaged with the do L, reacting on the dog for swingingthe og and the target about the pivot stud in the direction fordisplaying the signal Oil at the signal aperture, E and the target isprovided with a pin, 8, which projects through an arc slot E in the faceplate to limit the swing of the target, the p1n being accessible outsidethe face plate for restoring the target to signal-concealing position. aThe spring, M, besides reacting in the manner described for swinging thetarget about its. pivot, re-

acts upon the dog for swinging it upwardly about the pivots of the dog,L, that is, to

thepo'sition at which the nose of the dog will be in the plane of thetrack, In, an

\ adapted to ride thereon.

The knob, J, has appended to it a disk, K, of suitable diameter andsuitably positioned to cover and close the aperture, E through which thesleeve shaft emerges through to the face plate, and upon the face plateis a circle around the margin of the disk, K, there is imprinted amileage scale which in the present instance is graduated from 1 to 200,the graduated portion occupying such a proportionate part of the entirecircle-as 200 is of the mileage which would be indicated by the odometerin one complete revolution of the shaft, 6 which, as above ndicated, ismore than. 200 miles,

thus leaving a small sector of a circle without graduation.

The operation of the device for the purpose indlcated is asfollowsr Thenormal position of'theparts is designed to be with the target atsignal-concealing position; and upon its being moved to that position bymeans of the pin, 8, it will be seen that the dog, L, will be swung outradially with respect to the disk, K, and that thereupon the spring, M,Willcause it to swing laterally over into the plane of the track, is;and a stop pin, Z is provided on the hub, F, of the target, to check thedog at that osltion, preventing it from swinging farther in thedirection of the stress of the spring. ,The operator will now turn theknob, J, to' bring the index mark, 9' to the figure onthe graduatedscale, 4, which denotes the number of miles of travel which shouldelapse before the next attention will be required to the matter whichthe signal indicates,-in the present instance, the oiling. .If inthisadjustment the notch, 70 in the track, 7:, is carried past the nose ofthe dog, the target" will be operated and set'at signal-displayingposition, and the operator Wlll thereupon, after completing theadjustment by means of the knob, reset the target to signal-concealingposition, which will cause the dogs nose to be lodged uponthe track, k,at'a distance from the notch, 70*, in the direction of rotation of thedisk corresponding'to the number of miles for which the operator has setthe disk as above. described; and when. the odometer has been operatedby the travel of the vehicle that number of miles, the notch, 70 havingreached the nose of the dog, the target will be operated and swung tosignal-displaying position, and the nose of the dog will thereafter rideupon the track, k until the operator, having performed the requirementindicated by the signal, resets the disk, K, and returns the target tosignal concealing position.

Figs. 8, 9 and 10 show a slight modification in respect .to the slopingshoulder for guiding the dog laterally after it leaves the outer track,70, for lodging on the inner .track, 70 In this form the notch, 70substituted for the notch, I0 of the previously described form, is cutentirely through the flange, la, the sloping bottom, is, being sub-'desired to reset it after tripping. And in this form, to preventpossibility of the nose 0f the dog being engaged by the abrupt sides ofthe notch in whichever direcliidri the 're' J which will be spring heldtoward and against the flange when the dog is riding on the-inner trackand theexpanded corner is rounded as seen at P, so that there isafforded a slight clearance between the side of the flange and thelateral edge of the dog, and the rounded corner, 1*, insures against theprojection engaging the side of the notch. Y j g It will'be obvious thatthe end of the slot, E encountered by the operating pin, 8, may berelied upon to control the position of the dog while the signal is atdisplay position and in that case the track, is, may be omitted from thedisk, K. An objection to relying on the slot for this purpose is that itinvolves more exact positioning of the dial in the case than isotherwise necessary. The same result of positioning the dog duringdisplay of the signal may be efiec'ted with out the track, 76 by givingthe arm of the dog a width in. excess of the width'of the tooth or nose,L, which will ride on the track, is, when the nose hasfidropped into thenotch, K. This expedient is shown in Figs. 11 and 12, the excess Widthbeing seen at L I intendit to be understood that my invention in thisrespect is not limited to a construction having the track, W, on thedisk, K, but includes any 1 suitable means for positioning the dogduring display of the signal.
